The invention relates to the technical field of steering systems, in particular to a stepless steering mode switching method for an electric power steering system. The method comprises the following steps: acquiring a driver hand torque, a steering wheel steering angle and a direction angular velocity signal through a sensor; obtaining a whole vehicle speed signal and a steering mode switching gear signal through a signal receiving device; a basic power assisting module, an active aligning module and an active damping module are adjusted through a calculation module on the basis of the current driving working condition and a steering gear signal, the request ratio of all the modules to a driving motor of the electric power steering system is changed, and the purpose of changing the steering hand feeling is achieved; a steering motor is driven to perform auxiliary steering through a motor driving module; the multi-gear stepless switching mode of the steering mode is achieved by adjusting the proportion of all the modules of the electric power steering system.

    本发明涉及转向系统技术领域,具体地说是一种电动助力转向系统无极切换转向模式的方法。该方法包括:通过传感器获得驾驶员手力矩、方向盘转向角度以及方向角速度信号;通过信号接收装置获得整车车速信号、转向模式切换档位信号;通过计算模块基于当前的行车工况以及转向档位信号,对基础助力模块、主动回正模块、主动阻尼模块进行调节,改变各模块对电动助力转向系统驱动电机的请求配比,达到变化转向手感的目的;通过电机驱动模块,驱动转向电机进行辅助转向;通过对电动助力转向系统各个模块进行配比调节,实现转向模式多档位无极切换的方式。
